ABSTRACT:
The invention relates to a swimming pool monitoring device which can be attached to the wrist or other place on a child to constantly transmit an electromagnetic radio wave of a desired frequency. The monitoring device contains a water submersion sensor, which will deactivate the transmitter upon submersion. Whenever transmissions from the monitoring device are interrupted, due to immersion or battery failure, a receiver will sense this condition and activate an alarm, which may be visual, audible, or a signal that is relayed to further remote wireless equipment such as a pager or telephone dialing equipment that is used to dial an emergency telephone number.
